Although the eighth and final Harry Potter film actually sold less tickets than The Dark Knight, its debut was bolstered by the franchise’s first venture into the 3-D trend. Domestically, Transformers became the first film of the year to cross the $300 million mark, but it looks like Harry Potter will be gaining in Michael Bay’s rearview mirror soon and likely to overtake the action juggernaut for biggest film of the year as it’s on pace to tally $1 billion in the domestic box office alone. Winnie the Pooh couldn’t find the money pot in its opening weekend, and Woody Allen’s Midnight in Paris quietly became his top domestic earner.
